UNDERFRA'ME CONSTRUCTION FORCARS- Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filedFebriiary 12, 1906. Serial No. 300,756.

' which it appertains to make and use the same.

My invention relates to met-alliccarunderframe-constructions, and is in some respects an improvement upon my three prior patents, Nos. 763,841, 763,947, and 794,274.

The object of my invention is to provide an underframe construction for a car of the type illustrated in my above-mentioned pat.-

-ents in which a central girder with longitudinal cross-bearers is employed in combination with normally level fioor-d oors hinged at or near the top of the central girder adapted to swing down at the sides of the car to discharge the load, which can be easily and cheaply made from a relatively small quantity of material, which is very rigid and firm when constructed, is efficient-in operation, and is not readily liable to get out of order. It consists'in the novel method of supporting the side sills of the car, in the novel form of hanger for the operating-shaft, in the novel form of bracing for securing the cross-bearers to the central girder, and in other details of construction which will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a central sectional detail view of a car of the type illustrated in my above-mentioned prior patents, and particularly the one having the door-opcrating mechanism of Patent No. 763,841, embodying, the improvements of my invention in their preferred form. Fig. 2 is a somewhat enlarged detail View of'the hanger mechanism appearing at the left of Fig. 1. Figs. 3, 4:, and-5 are detail parts of the device of Fig. 2 shown separately. Fig. 6 is' a detail perspective view of brace-plates connecting the central girder and cross-bearers. Fig. 7 is a detail perspective view of a novel form of top plate for the cross-bearers, showing means forsecuring it to the stake and for supporting the side sills of the cars upon them. Fig. 8 is a central. sectional detail view of a modified form of car in which the central girder is made deeper than in 1,

the same extending up into the underframe,

- rivets 36.

secured thereto are the intermediate portions.

13 of braces 32. Across the top of this central girder, extending from side to side of the i car, as in-my prior patents, are cross-bearers 15, preferably commercial rolled channelirons, having vertical webs and horizontal flanges 1'6 and 17 extending from one side thereof in the usual manner. These crossbearers are placed upon the central girder at approximately equal distances apart longi-' tudinally of the car, so that floor-doors 21 may be pivotally mounted between them in such a way that, as fully described in my prior patents, they will when swung up level with the tops of thechannel-iron cross-bearers form part of the'level floor of the car and that when swung down to the dottedline position of Fig. 1 they will be adapted to discharge the load at the sides of the car. These doors 21 are hinged upan a longitudinally-hinged rod 18, mounted in a plurality of castings 19, which are in turn mounted upon the I-beam 20, placed above the central girder and connected to the successive crossbeai'ers, as is fully described and claimed in my prior application, Serial No. 268,805, filed by me May 29, 1905.v The cross-bearers 15 are secured to and bracedi'rom the central girder by means of the novel form of braceplates 25 and 26 illustrated in detail in Fig. 6. These'plates have, as shown, vertical flanges 27, adapted to be secured to the side plates 1 1 of the central girder by bolts or rivets 2-8, bottom flanges 29, adapted to be secured to the bottom angles of the central girder and horizontal portions 13 of bottom braces 32 by means of the bolts or rivets 30, diagonalflanges 31, adapted to be secured to the upwardly-extending portions of the bottom braces 32 by-means of bolts. or rivets 33, and top lips 34, adapted to be secured to the webs of the channel-irons 15 by the'bolts or These platesare, as shown, very broad in their width perpendicular to the flanges 31, so that they have great bracing strength and in addition to supporting the cross-bearers in the ordinary way give the car great lateral rigidity. The plates 2-5 and 26 upon opposite sides of the central girder are connected together by means of cross plates 38, placed inside the central girder, the same having flanges 39, which are engaged by the rivets 28, heretofore described.

Over the top of each cross-bearer I place a suitable cover-plate or angle-iron 40, with downwamdiy turned' flanges 4-11, as is more.

fully. described and claimed in: my prior apiplication, Serial No. 262,805.v The coverplate is showm in; detail in Fig. 7, andgasshowni in Fig. 1, said plates have end por tions 453'. extending beyond'the ends at the" crossbearers, andsuitableside stakes; 454 are secured by belts or rivets 46 170 the ends oii I secureda thereto,- by means ofthe belts or rivets-51. Outside of the stakes and restin one theends 43' off the cover-plates 40' p ace side sills 53, preferably made of channel-irons, asshown, extending along the sides oh the car, and: secure the same-to thestakes by means of the-bolts or rivets 54 and belts or rivets 51. By this construction the stakes are-given a veryyigid attachment totheends ofi t 'ecross-bearers, and the" side sills are supported. by portions of the cross bearers, (the cover-plates 40,) as-welll asby their bolt or rivet attachment to. the stakes, alli of which. givesa very strong yet economical: construction;

The operating mechanism for the floordoors 21' is that of my; said-1 rior patent, No. 763; 84: 1, inwhich a longitu inal-i shaft 60,

- with. a. plurality of crank-armahl and; intermediate common crank-pins 62, carrying rolls 63, bearing upon the= under side oh the successive-floor-doors, is used, the same be ing supported in suitable hangers upon the under side of thee, underf'rame, the form: of which: here shown is a part of my invention. These han ens consist of: single pieces 01' metal bent 1n. the fOIlID ofi arY', with the bear-' ing for-the shafit'upon the lower end oli each hanger. Indetail! they consist of. said hangers-having flanges 66;and:'67, secured to the lower flanges: of. the cross-bearers by bolts or rivets, 68, having also: the inclined angular portions=69-and 7-0 of theY andfthenormally opened. upturned bearing portion- 71 at the lower end of the Y, in. which: the shaft ($0, hGIfCtOfOlBQZGfGITBd' to rests and is 'o'urnaled'. These hangers are made'more ri i uponrthe under'sideot the cross-bearers by meansof.

the flat plates 73, secured to the webs oi the cross-bearers by bolts or rivets 74, as shown, the plates themselves depending below the cross-bearers and having angular wings or lips 7 5-and Z6 fitting in and engaging the angular portions 69 and of the Ys and secured thereto on the side by bolts or rivets 78 and on the other side by removable bolts 7 79, adapted to secure in position removable angular pieces 80 having one arm adapted to fit under said bolt and theother arm adapted te -bear against theshaft 6O andisocure the shaft in thebearing, as shown. By this construction I! obtain: a very cheaphanger which: is very rigid. upon the under side of the crossbe'arers, thereby rendering the shaft more accurately operable.

In Fig; 8 I have shown a modified form of structure using the bracing of my invention in. which the central: girder extends up into the'und'erframe of the car and. t-lio-topiplates :82 u on the cross-bearers extend. through .slbts 1nthe vertical; web plates of the central girder.

It is: evident that many slight changes might be made in. the relativearrangement of parts shown and; described: without departing from the spirit and scope of my in.- ventiorr. Jzlence I would have-it understood that I do not wish tOzGOIlfiIlE myselt to the exact construction herein shown and: de
